You’re a big star and you don’t like the line you’ve been asked to say in a movie. What do you do? Call in your own “personal writer”. More and more stars are working with their own writers on the set. “While these kind of personal writers may be well-known inside Hollywood, they often toil in public obscurity. Don’t shed any tears, though. Even without screen credit, top rewrite artists can bank more than $250,000 a week for script revisions and frequently can stay on a movie for months at a time.”
